Abstract

The invention provides a polymer solar cell and a preparation method thereof. The polymer solar cell comprises a conductive anode substrate, a hole buffer layer, a first active layer, an n-type layer, a p-type layer, a second active layer, an electron buffer layer and a cathode which are laminated in turn. The material of the n-type layer is the mixed material formed by lithium salt, poly 3,4-ethylene dioxythiophene and poly p-styrene sulfonic acid. The material of the p-type layer is the mixed material formed by poly-3 hexyl thiophene and phthalocyanines micromolecule. The polymer solar cell is higher in utilization rate of sunlight and energy conversion efficiency. According to the preparation method of the polymer solar cell, preparation technology is easy to control, industrialized production of devices is facilitated and processing cost is low so that commercial development prospect is quite wide.

Description

technical field [0001] The invention belongs to the technical field of organic solar cells, and in particular relates to a polymer solar cell and a preparation method thereof. Background technique [0002] In recent years, solar cells using organic small molecular compounds and polymers as semiconductor materials have become a frontier issue in the field of organic optoelectronic functional materials and devices. Among them, polymer solar cells have the advantages of simple manufacture, low cost, low toxicity, rollability, and large-area preparation, and have broad development space. [0003] A polymer solar cell with a multilayer structure includes positive and negative electrodes and a thin layer with photoactivity between them, that is, the active layer. The active layer generally has a heterojunction structure composed of a donor (D) and an acceptor (A). Usually A p-n heterojunction structure is adopted, that is, a p-type material is used as a donor and an n-type materi...
